Restrictions on the use of EXEC CICS commands

The commands that a terminal error program (TEP) can issue are restricted. In particular, you should avoid commands that require a principal facility, as they cause unpredictable results.

Do not use commands that invoke the following functions:
  • Terminal control (“CEMT-type” commands, such as EXEC CICS INQUIRE TERMINAL, are permissible)
  • BMS (except routing)
  • ISC communication (including function shipping).
